You'll want to do something like this:

NSDateFormatter * inputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ];
NSDateFormatter * outputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ];
[ inputFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss'.000Z'" ];
[ outputFormatter setDateFormat:@"EEE, MMM d, yyyy h:mm a" ]; 

NSString * inputString = @"2009-11-23T05:24:41.000Z";
NSDate * inputDate = [ inputFormatter dateFromString:inputString ];
NSString * outputString = [ outputFormatter stringFromDate:inputDate ];

// outputString = @"Mon, Nov 23, 2009 05:24 AM"

See the Unicode date format patterns guide for more information on how to configure NSDateFormatter.
